Oklahoma has averaged 3.1 yards per rush through seven games. South Carolina has allowed 3.3, giving the Gamecocks a useful matchup to keep the Sooners from pulling away on the ground.
The Sooners have scored touchdowns on just 6 of 17 red-zone trips this season. South Carolina +5 leaves room for Oklahoma to move the ball without consistently finishing drives with touchdowns.
LaNorris Sellers adds a rushing threat Oklahoma has to account for alongside South Carolina's running backs. He threw for 279 yards and 4 touchdowns at Florida, then ran for 96 yards and 2 touchdowns against Tennessee.
Against Tennessee, South Carolina also allowed just 3 points after halftime. Dylan Stewart's late forced fumble set up Malik Orsan's winning 48-yard field goal.
